To all whom it ma concern: I

Be it known that LESTER KIRSCHBRAUN, a citizen of the United States, residing in the city of Evanston, county of Cook, and 5 State of Illinois, have invented certain new and useful Improvements in Roofing Elements, of which the following is aspecification.

This invention relates to improvements in roofing elements and process of making same, and is more particularly adapted to that type of roofing element commercially known at cross-cut shingle strips, such as are shown in patent to F. C. Overbury, N0.

1,150,298. The essence of the present invention consists in making a shingle strip which will simulate a plurality of shingles but -which, insteadof being notched as in said.

Overbury patent, is slotted along that por- 2 tion of the strip corresponding to the notched portions of said Overbury patent,

the slots, however, terminating in closed ends at the edge of the strip instead of having notches open at one end. By doing this, a reinforcement is obtained along the entire edge of the strip so as to produce a strip having uninterrupted edges. This will also tend to prevent curling of the shingles after laid on the roof.

In the drawings, Fig. l is a top plan view of the completed product. Fig. 2 is a sectional view taken at lines 22 of Fig. 1.

Referring to the drawings, 1 designates the foundation or backing of the strip, 36 which may consist of ordinary asphalt saturated felt. This is provided with usual coating 2, ,to which is adhesively secured the granular facing 3. This granular facing is applied over the entire face of the roofing in the same way as roll roofing is and the roofing sheet may then be slotted as shown at 4:, these slots terminating short of the front edge of the strip. Each slotting knife, which may be mounted on a rotating cutter, may be also provided with a boss portion to force the granular black paint, the result being that when the shingle strips are laid in the usual overla pmg manner on the roof, they will give t e appearance of separated shingles, the black portion 5 blending into the slotted portions and simulating a completely cut edge.

I claimas my invention:

1. A shingle strip having a felted fibrous base coated with an adhesive material, a granular surfacingapplied thereto, slots extending transversely across saidstrip near one end, and terminating short of that end to present an unbroken closed lower edge when the shingle is laid, the connecting unbroken portions thus provided being of a difi'erent color than the major color of the strip.

2. A shingle strip having a felted fibrous base coated with an adhesive material, a granular surfacing appliedthereto, slots extending transversely across said strip near one end, and terminating short of that end to present an unbroken closed lower edge when the shingle is laid, the closed portions adjacent the slots having the granular surfacing pressed into the adhesive material.

3. A shingle strip having a felted fibrous base coated with an adhesive material, a granular surfacing applied thereto, spaced interior slots extending transversely across said strip near one end, and terminating short of that end to present an unbroken closed lower edge when the shingle is laid, the connecting unbroken portions thus provided between the slots having the granular surfacing pressed into the adhesive material, these webs exhibiting a darker color. than the color of the sheet.
